Export/Import using the PublishingService

To allow automated translation of content SharePoint provides the export and import funcationality also through the ExportObjects and ImportObjects methods of the PublishingService web service which can be accessed using the following URL:

http://servername/site/_vti_bin/PublishingService.asmx

There is good documentation on how to use the web service for export and import on MSDN:

But to convert this to PowerShell methods take some effort and I havn't seen this done. I would write Console application instead to solve the problem at hand if you don't like to use Export Translation in your SharePoint GUI.
